'''Léon Bollack''' (1859 – 1925) was a rich French trader who created ''The Blue Language'' or Bolak (Blue Language)|Bolak in 1899. After a few years, he joined the Ido (language)|Ido movement; it is possible that the blue color of the Ido flag was his proposal. He uttered the phrase: "It seems to me that both the Esperanto and Volapük poets are worthy only to be the objects of ridicule." Bollack inspired H.G. Wells who mentioned him in his book A Modern Utopia. He died in 1925.
